Quite simply insulation works to keep the outside temperature out and the inside temperature in. Think of it like a chilly bin or vaccuum flask, if you put hot food in it stays warm and if you put cold food in it stays cold. It works to stop/slow temperature transfer – just like putting a jersey on when it’s cold. The better the grade or type of product you use the less temperature transfer there is so the better it works (like putting on a thicker or better jersey suited to the environment you are in). Insulation does not create any energy of it’s own so it wont heat your home but it will help retain the warmth you generate thus creating better internal living conditions. So many of our customers are very surprised by the difference it makes.
Hot air rises so a lack of, or inadequate ceiling insulation can be responsible for considerable heat loss in the home (around 46% and up to 60% in older homes). When you flick on the heater you want to make sure that expensive heat stays in. Lack of insulation can also make your home hotter in summer as the heat from the attic space transfers into the home. Wall insulation works in much the same way although less heat is lost through the walls (around 25%).
No insulation installed. Warm air easily escapes through the ceiling.
Insulation installed between joists. Offers some protection, however warm air is still lost through the joists.
Insulation installed between joists with blanket over the top. The blanket insulates the ceiling joists offering complete protection.
Underfloor insulation works extremely well in older homes with wooden floors. Statistics say that between 10-15% of heat is lost through the floor but the impact on your home is normally much greater than this. Why? – as the earth chills down so to do your floors which is transferred through into your home. By putting a ‘barrier’ to slow or stop this transfer the home doesn’t cool down nearly as much in the first place making it easier to heat. By also blocking out rising dampness the air inside is dryer and hence easier to heat. Most older tounge and groove wooden floors have gaps allowing drafts which is a major form of heat loss.
No insulation installed. Warm and cold air passes freely through the floorboards.
Insulation installed between joists offers some insulation. This produces an “incomplete thermal envelope” as warm and cold air passes through the joists.
Insulation installed as a blanket. The trapped air pocket significantly boosts thermal performance creating a “complete thermal envelope”.
Wall insulation works in a very similar way to ceiling insulation but because less heat is lost through your walls the impact of insulating your walls is less than insulating your ceiling. To install wall insulation without removing the internal lining involves the drilling and injecting of foam type products. If your internal lining has been removed it is as simple as cutting and placing sections of insulation between your wall studs. Product options
